What distinguishes us from the first homo sapiens?

The oldest remains found of homo sapiens date back to 195 thousand years ago; since then our skeleton has not substantially changed, but this not applies also to the rest of our anatomy and, in particular, possible changes in our intellectual capacity would be very difficult detectable by the shape of the skull. Considering that our species has begun to spread out from Africa about 125 thousand years ago, one can deduce that the current ethnic differences should have been necessarily formed after that time. Since these differences can be observed in facial features, hair color or stature but not in the intellectual capacity, we can say that this latter had already been developed before the migration in the continents. Given that every human generation feels much more intelligent than previous ones, starting with that of their parents, it is difficult to imagine ourselves sitting on a bench in our jacket and tie, with a mobile phone in our hand, aside of a homo sapiens of 125 thousand years ago in wolf skin, with a cudgel in his hand and being convinced he has a brain with the same genetic ability; the truth is that differences are only the result of cultural evolution, of that cumulative culture that distinguishes our species and that, increasingly quickly developing, can now really lead to a significant differentiation between two successive generations.
